Embodiment 1
[0045] Such as figure 1 , figure 2 , image 3 , Figure 4 as well as Figure 5 As shown, the present invention provides a touch module 100, the touch module 100 includes a cover plate 110, a display layer 120, a piezoelectric layer 130 and a touch control layer stacked between the cover plate 110 and the display layer 120. Layer 140, where:
[0046] The cover plate 110 can completely cover other structural components. The cover plate 110 can be made of a transparent material, and the cover plate 110 can be selected from a material with an acoustic impedance close to that of the display layer 120, such as any material such as a glass plate, a stone substrate or a plastic film. A layer structure that can come into contact with a touch object (such as a user's finger);
[0047] The touch layer 140 includes a touch IC142 and at least one TFT electrode layer 141 electrically connected to the touch IC142. The TFT electrode layer 141 is used to form an inductive capacitance and...
Embodiment 2
[0075] In addition, the present invention also provides a smart terminal, including the touch module 100 according to any one of the above technical solutions and a casing, and the touch module 100 is disposed on the casing. In specific settings, the display device in the present invention can be used in various smart terminals, such as smart phones, smart bracelets, notebook computers, tablet computers, vehicle-mounted displays, etc., which are not limited here.
[0076] In the smart terminal mentioned above, the piezoelectric layer 130 and the touch layer 140 are stacked between the cover plate 110 and the display layer 120 to form the touch module 100. In the touch module 100, the cover plate 110 is used for To protect the structural components located below it, the TFT electrode layer 141 in the touch layer 140 can form a sensing capacitance and a first electric field when the cover plate 110 is pressed, and the sensing capacitance can analyze the touch position information...
